Description

DETAILED DESCRIPTION OF THE INVENTION FIELD OF INDUSTRIAL APPLICATION This invention relates generally to the field of excavating clam-type grapples, and more specifically to the field of grapple grapples for active operation and control of grapple jaws. Grapple connector heads and attachments involve assembly.

BACKGROUND OF THE INVENTION Those skilled in the art will appreciate that known packet or crumb attachments for drilling have a number of drawbacks. In this type, one jaw is fixed so that the Talamusiel-type grapple is limited when processing rocks, trash, undergrowth, logs, stumps, etc. This type of grapple is only suspended from the end of a boom or dipper shaft and does not allow active control in at least one dimension. Other types of talam shell baskets or grapples may also be too complex and therefore too costly or virtually impossible to use for their intended purpose. In either case, they fail to provide the versatility and flexibility essential to saving labor and time.

[Summary of the Invention] In the present invention, a dipper shaft and a packet shaft of an excavator are provided.
Contains a connector or mounting head that attaches to a linkage or Clarada arm. A mounting rotatably couples the assembly to the connector head. Installation is done by assembling and grappling jaws in succession.
A water (hydraulic) motor is provided to rotate by 60°.

The installation attaches a cylinder to the assembly to open and close both grapple jaws. Furthermore, a control device is provided to control the rotational movement of the grapple and open/close the jaw. SUMMARY OF THE INVENTION It is therefore an object and feature of the present invention to provide a grappling device that can be accurately positioned on rocks, logs, pipes, etc. and exhibits excellent flexibility and versatility in mining and trenching. This is an advantage.

Because the present invention is actively attached to the boom or dipper shaft rather than simply suspended from it, the Abelator is able to transfer the full pressure of the boom or dipper shaft to the grapple below. By employing the grapple of the present invention, relatively large objects can be removed without moving the excavator, and this work can be carried out in the excavator rather than within the triangular stirrup as seen in many known grapples. This can be done within the rectangular work area on the machine side. The device of the invention is simple, relatively low cost, and extremely robust. The grapple of the present invention facilitates the removal of stumps, the laying of stone foundations, and the construction of rock structures using large boulders, thereby reducing the time required for these operations. Furthermore, by employing the grapple apparatus of the present invention, an operator can work from a remote location, which was previously not possible.

To do this, we will add two control levers to the excavation type.
This provides complete flexibility of operation.

[Embodiments] Preferred embodiments of the present invention will be described below with reference to the accompanying drawings.

As is apparent from the drawings, the grapple 10 is connected to the excavator shaft 12 via the main connecting pin 14, while the linkage 20.22, piston rod pin 24
and is connected to the tool cylinder piston rod 18 via a connecting pin 26.

The connector head 30 consists of two side plates 32.32 which are spaced apart from each other, and the upper ends of the side plates 32.32 are spaced apart from each other to sandwich the dipper shaft 12.

As can be seen from the drawings, the side plates 32,32, which are arranged substantially parallel to each other, are connected to the connector head substrate 34. Although the shape of the substrate 34 is arbitrary, FIG. 5 shows a substantially rectangular shape. The side plate 32 is arranged so as to separate the connecting pins 14, 26 and so that the connecting position of the bin 26 is higher than the connecting position of the main connecting bin 14, as is clear from FIGS. 1 and 2. It's in shape. Below the pin connection part there is a reinforcing plate 38 that connects the side plates 32, and this reinforcing plate 38 almost completely occupies the area between the side plates 32 and limits the inner area. Board 3
There is a frontage part 42 in the center of 4. Holes 1 to 44 are arranged at equal intervals near the opening 42, and a series of holes 45 are formed in the substrate so as to surround these openings 42 and holes 44 concentrically. 34.

As is apparent from FIGS. 3 and 5, the water (oil) diversion valve assembly 50 includes an elongated valve body 56 and an upper end thereof.
Equally spaced bolt holes 54 that match bolt holes 44 in substrate 34
It is a generally cylindrical component having a mounting flange 52 with a perforated mounting flange 52. The valve body 56 extends downwardly from the mounting flange 52 to a pivot bearing 58 made of plate steel or brass that rotates on a wear ring. Holding plate 6
0 and the cap screw 62 connect the rotatable bearing 58 to the valve body 56.
Fixed to. Water (oil) pressure passages 64,66 respectively pass through the rotary valve body 56 from couplings 68,70 connected to water (oil) pressure supply pipes 72,74. When under pressure, the other tube 14 or 72 acts as a liquid return tube.

There are annular passages 76 and 78 within the rotatable bearing 58;
Each is equipped with a person exit (p. 79.80 and p. 82.
It opens at 84. The annular passage 76 is connected to the supply passage 64
Connect to. The annular passage 78 is connected to the mounting u-section 82.84.
It is also connected to the supply passage 66. Seal members 86 are provided above and below each of the annular passages 76 and 78 to prevent leakage of high pressure hydraulic fluid flowing toward the grapple cylinder. Since the water (oil) bypass valve is adopted, there is no need to worry about overextending hoses or other water (oil) pressure pipes, or having to reverse the direction of rotation due to the limit of rotational movement. The grapple 10 can be rotated 360° in a continuous circle.

As seen in FIGS. 2 and 5, the zeta gear/bearing assembly 90 is coupled to the connector head 30 7-t! While I am disappointed, I will discuss the details later, #110
is also combined. The gear/bearing assembly 90 is connected to the substrate 3
4 includes a bearing portion 92 drilled with a bolt hole 94 aligned with hole 45 of No. 4. A ring gear part 96, which is rotatable relative to the bearing part 92, has a bolt hole 98 and is provided with teeth 100 on the outer circumferential side. If desired, the teeth may be provided on the inside of the ring gear, in which case the bearing portion would be on the outside. The gear/bearing assembly 90 is well known and is not shown in detail.

A water (oil) positive drive motor 102 is attached to the outside of the substrate 34 so that its shaft passes through a hole in the substrate 34, and a binion gear 104 that meshes with the teeth 100 of the ring gear is attached to its end. As shown in Figure 2, water (
The positive drive motor 102 is provided with a suitable water (hydraulic) connection groove. If desired, the gear/bearing assembly 90 may be of the type with the ring gear on the inside and the bearing on the outside, in which case the water (oil) positive drive motor 102 is mounted in the space between the side plates 32,32. I'm going to have a good time.

The mounting assembly 110 described below is particularly suitable for the first
As is clear from FIG. 1, M2, and FIG.
